It is said that every American who was alive in 1963 remembers exactly what he or she was doing at the moment they heard the news of President Kennedy being shot. Then, less than an hour later, came the awful report that he had died. It’s hard for anyone who was not a witness to those sad days to fully comprehend the sense of loss which overtook the nation. This grief found expression in the renaming of many civic structures, roadways and even geographical features in honor of the slain leader. Of all these memorials, however, the United States half dollar bearing Kennedy’s familiar likeness will almost certainly survive the longest, since coins, being nearly indestructible, have a long track record as the most durable witnesses to history.
